Cameron Diaz and Stella McCartney at Lunch in London

Cameron Diaz Celebrates Stella's 41st With Lunch

Cameron Diaz and Stella McCartney wore matching boots.

Cameron Diaz and Stella McCartney wore matching boots and bags for lunch in London today. The girls each sported platform boots created by Stella herself, as well as two of the designer's much-loved Falabella bags. It seems Stella and Cameron were in great moods this afternoon, showing each other pictures on their phones and indulging in a midday glass of wine.

Their meal in Notting Hill came just in time to celebrate Stella's 41st birthday, which was yesterday. Stella's usually one to mark her milestones with a big bash — last year, Gwyneth Paltrow and Kate Hudson joined forces to toast Stella's 40th with a glamorous party. Cameron's catching up with her UK pals while work has her in London. She's currently shooting Ridley Scott's The Counselor along with Brad Pitt, Michael Fassbender, Javier Bardem, and Penelope Cruz.
